Fractional Product Designer

About

I’m a product designer who operates like a fractional design lead, embedding with teams to drive research, product direction, and UX strategy. I specialize in turning ambiguity into structure, building scalable systems, and helping organizations translate customer insight into product decisions. Alongside client work, I’m building AI-first tools to modernize how teams synthesize and use research.

AI Design process

Research Synthesis

Today, I still use Dovetail as part of my research synthesis process, while gradually integrating Peridot into my daily workflow. I use Peridot to upload interview files, automatically generate insights, and create highlight reels within seconds. This allows me to quickly pull direct quotes, identify patterns, and summarize themes across interviews in minutes rather than hours. These highlight reels can be shared with the team for review, or explored directly in Peridot so stakeholders can interact with the underlying data themselves. Once insights are synthesized, I organize them into a short presentation to align the team and inform design direction.

Design Exploration

When I'm tackling complex design challenges and need inspiration, I use Vercel's V0 or Figma Make to spin up multiple design variations. In a matter of minutes, I'm able to test different UX patterns, layouts, and visual systems without overcommitting to one version.

Rapid Prototyping

In my experience, users are more engaged during usability tests when they can input real data, not just click buttons. After finalizing designs in Figma, I use Figma's MCP Server to push them into Cursor, then deploy them live on Vercel. It takes 15-20 minutes to get a prototype up and running. Usability sessions feel more authentic, and feedback feels richer and more specific.
